AGFL

[AGFL for GNU — concluded in 2002]

With the AGFL (Affix Grammars over a Finite Lattice) formalism for the syntactic description of Natural Languages, very large context free grammars can be described in a compact way. AGFLs belong to the family of two level grammars, along with attribute grammars: a first, context-free level is augmented with set-valued features for expressing agreement between parts of speech. The AGFL parser includes a lexicon system that is suitable for the large lexica needed in real life NLP applications.
